The NE declares a URU-S failure against each associated STM-n line on a failed circuit pack if a circuit pack failure defect persists for the alarm processing delay period ± 0.5 seconds. Refer to SET-ATTR-ALM:almdel in Alcatel-Lucent 1850 Transport Service Switch (TSS-5) TL1 Command Guide for MSPP. Upon declaring and the failure, the NE sends an alarm message to the appropriate OS(s). The NE clears a URU-S failure when the CP failed defect clears. After clearing the failure, the NE also sends an alarm message to the appropriate OS(s).

Description |
underlying resources unavailable, equipment |
|
Likely Cause |
The URU-S alarm(s) is declared coincident with a CP failed alarm. An unprotected circuit pack carrying service failed: MJ: SA. A protected circuit pack failed or an unprotected circuit pack NOT carrying service failed: MN: NSA. |
|
Visible Indication |
Lighted CR/MJ or MN/ABN LED on SYSCTL faceplate and a flashing FAULT LED on the failed circuit pack. |
|
Action |
In the alarm list, find the associated CP failed alarm, and proceed to Procedure 5-9: Clear "CP failed" alarms. |
